Key benefits
- Room for a restless partner: At 90cm each, you get 15cm more width per person than the UK king, which means a partner's turning is far less likely to reach your side.
- Space when children or dogs join: The 6ft x 6ft 6in surface leaves enough width for a small child or a large dog to settle without either adult ending up clinging to the edge.
- Zoned support for both sleepers: The seven spring zones shape support to each body separately, so both of you get the same targeted support across the full 180cm.
- Proportioned for a large room: In a big master bedroom or a high-ceilinged older home, the UK super king fills the floor in proportion where a UK king can look a little small.
- Standard bedding sizes: Super king sheets and a 260 x 220cm duvet fit, so you're buying widely available sizes rather than searching for specialist bedding.
This size suits you if...
You share with a partner who moves a lot and want real distance between you, your children or dog regularly end up in bed by morning, or your bedroom comfortably clears 3m x 2.9m and a smaller bed would look lost in it.
Consider another size if...
Your bedroom is under our suggested 3m x 2.9m, or tight stairs make carrying a flat 180cm mattress risky. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Will a Millbrook Sovereign super king fit up my stairs?
Measure first. This mattress isn't rolled and boxed, so it stays flat at 180cm wide and 31cm deep. Check landing turns, the narrowest point of the stairwell and which way the bedroom door swings. If any of those look tight, the UK king is 30cm narrower and the same length.
How big a bedroom do I need for a UK super king Millbrook Sovereign?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable. That leaves room for bedside tables on both sides and space to walk round. In a loft conversion, the sloping ceiling usually decides which wall the bed goes against, so measure the full-height floor area rather than the whole room.
Is a UK super king big enough for two adults and a child?
For occasional visits, yes. Two adults get 90cm each, so a toddler wandering in at night still leaves everyone a usable share of the bed. If an older child sleeps with you most nights, it will feel a little crowded, although far less so than on a UK king or UK double.
Super king or king Millbrook Sovereign for a restless partner?
If restlessness is the main problem, the UK super king. Both are the same length, so the only difference is width: the UK super king gives you 15cm more each. With a partner who kicks or turns often, that extra distance does more for your sleep than the pillow top's cushioning.
What sheets fit a Millbrook Sovereign super king mattress?
You'll need super king fitted sheets and a 260 x 220cm duvet. The mattress is 31cm deep, so check the fitted sheet's pocket depth suits that before buying. Bedding at this size costs more than for smaller beds, so budget for it alongside the mattress.
